I can’t perfectly repeat every song I’ve ever heard so many of the files would be garbled, but it’d have to be at least a few hundred GB for that, the text of a few thousand books, stills/video from several hundred movies. Add in all the subconscious things humans analyze every day including facial expressions and you have myriad data.
